MP3. I regret it, because I expected during my first listening test in 2003 a massive support of new formats in hardware players. Situation is getting better and better, but in 2006 MP3 is still ruling the marking with minor issues (tag mostly) compared to Vorbis.Lossless & mp3 (lame) for me.

No problem. It couldn't have been easier!...I didn't realize this is where the lowly forum plebians could post polls....I suspect if it meets the approval of the mod gods, that it will get moved to the Poll forum.

Thanks to the likes of Iriver, Iaudio and Rockbox for the Ipod, I am happy to say that Vorbis is flying high in my personal collection.

MP3 - sounds good and works with everything. Maybe if my future devices support a format sounding as good as LAME -V2 at half the bitrate, I'd think about switching. Until then, I see little point in dumping my MP3's.

I haven't made a single ABX testing with Vorbis, Mp3 and other formats, but Mp3 is so hardware supported, so standard in industry and with so great quality when i'm listening to, that i'm still stuck with it.

I've been doing some encodings with vorbis tough, but mainly from lossless sources and pc only enjoyment.

I rip CDs and encode to lossless (FLAC these days) and keep a copy on a computer with a very large hard drive. I encode them into smaller lossy files as required.I tend to prefer Ogg Vorbis, as I can play them in my Treo 650, and small files are a good thing!

The only things keeping me using MP3 at all are:-I use DJ software that is badly out of date, and still doesn't support anything other than MP3 and WMA (BPM Studio Professional by AlcaTech) but they claim that they will support Ogg Vorbis and not AAC in the next version.-A friend I share my files with insists on MP3, mainly just because that's what she already has in her collection. (She's not nearly as computer savvy as myself though).

AAC is promising too, but it's a pain in the ass to use, and it always costs money in every instance of an encoder or decoder, which I'd rather not bother with. I do think that the quality is better for ultra-low bitrate lossy encoding.

mp3 is all my player supports unfortunately, so thats what i use mostly. i like to use ogg sometimes, because i know i can get transparent encodes at 128kbps or below. even more so now, because i use linux, and it just feels right. i hope to switch to ogg completely eventually, when i get a new dap most likely. but as for now, i'm satisfied with the quality of mp3 at -V4 or -V5, and mp3 does have the great advantage of being able to be played on any of my friends computers, as sadly, most of them use itunes or windows media player (aka windows media virus).

i know its ot, but i proudly use wavpack for archiving. its features are unbeatble.

Still using MP3, mainly because of hardware support.Even though more and more products (mostly, in mobile phones market) start supporting AAC, they are still not fully compatible with it. For example, W800i support both AAC and MP3 but only MP3 tag can be read.
